WINDINGgAND REELING MACHINE.

Original application filed August 21,"!925, Serial No. 51,804 Divided and this application filed January 15,

1926. Serial No. 81,435.

This invention relates to machines for. winding and reeling various fibrous materials and especially adapted for winding or reeling silk, and has for its object to provide a stop motion controlled .mechanism in which a new and improvedelectrically operated means is employed for automatically stopping the winding operation when for any cause a thread breaks, the supply becomes exhausted. or a predetermined amount of material has been wound or reeled.

Another object is to provide a registering device which may be set at a predetermined point to electrically operate a signal and sto the winding mechanism.

nother object is to provide certain improvements in the form, construction and arrangement of the several parts whereby the above named and other objects may be effectively attained.

A practical embodiment of our invention is represented in the accompanying drawings, in which Fig. 1. represents a detail-vertical section of one end of a reeling machine having the driving mechanism and adjacent parts to which our improvements have been applied,

certain of the parts being broken away to show other parts more clearly.

Fig. 7 represents a vertical section taken in the plane of the line VIIVII of Fig. 6, and

Fig. 8 represents asimilar view showing the part-sin another position In the drawings, we have illustrated our invention as applied to a reeling machine, of which only one end has been shown, it being obvious that standards and end frames serve to support the opposite end of the several shafts. rods, bars and shelves in brackets, together with hearings similar tothose hereinafter described.

A portion of one of the vertical standards of the machine is denoted by 1, and the horizontal shelf by 2, which extends from one standard to the next standard.

The supply spools are mounted on pins 3 carried by the shelf 2. The thread 4 from each spool passes upwardly to a guide rod 5, and downwardly over guide rods 6 and 7 thence through a loop 8 of a detector or faller 9, and through guide eyes'lO carried by a reciprocating traverse bar 11 to a reel 12. The detectors or fallers are each mounted to independently rock on a rod 13 fixed in and between the standards. Each detector is so arranged that while a thread is passing through the loop 8, the detector will be -held against a stop rod 14, but when the thread breaks, the detector will be released and caused to fall by gravity to rest on a bar 15 carried bybrackets 16 depend-- 'tate with a pulley 17 in any well known or approved manner, which pulley is secured to a stud shaft 18 carried by a swinging arm l8" pivoted on a stud 18" fixed to the standard 1 as shown in Figs. 6 to 8 inclusive. Power is applied to a drive shaft 19 from a suitable source (not shown), which shaft has mounted to rotate therewith a pulley 20 arranged in position to frictionally drive the reel pulley 17 on the stud shaft 18, in the usual manner.

Motion is imparted to the traverse bar 11 from the stud shaft 18 through spur gears 21, 22 and bevel gears 23, 24 of which the bevel gear 24 is carried by an inclined shaft 25 mounted in bearings 26, 27 offset from the traverse bar 11 in the well known manner. V

A brake lever has one end pivoted on a pin 31 fast on the standard 1 and is provided with a friction pad 32 which is adapted to be brought into contact with the pulley 17 to lift the same so that it will contact with a friction pad 33 carried by a stud 34 fixed on the standard and arranged to overhang the pulley 17. The brake lever 30 is yieldably held in position by meansof a rod. 35 pivoted at 36 and extending downwardly through an ear- 37 secured to the standard 1, between which ear and adjustable nuts 38 threaded on the rod 35, a spring 39 is interposed. A latch 40 pivoted at.41, is arranged to engage a lug 42 carried by the brake let er 30 and yieldingly held in contact therewith by means of a spring 43. The brake lever 30 is also provided with a handle 44 by which it is manipulated to place the lug 42 and latch 40 in cooperative relation. The latch 40 is rocked away from the lug 42 by the following means:

A member 45 is pivoted at 46 and provided with a curved toe 47 which is arranged to coact with a finger 48 carried by the latch 40. This member 45 is also provided with an arm 49 having a weight 50 at its outer end, which is intended when free, to overbalance the member 45, rock the toe 47 and thereby actuate the finger 48 and latch 40. The weighted arm 49 is held in position, as shown in Fig. 2, by means of a bell crank 51 pivoted at 52, one end of which isprovided with a notch 53 arranged to engage a lug 54 projectingfrom the weight 50 on the arm 49. A depending arm 55 of the bell crank 51 forms the armature of an electromagnet 56 and is arranged to be actuated thereby. The electromagnet 56 has one pole connected by a wire 57 to the bar 15, while the opposite pole is attached to a spring contact finger 58, which coacts with a similar spring contact finger 59. This spring contact finger 59 is connected by a wire 60 to one pole of a battery 61 while the other pole of the battery has a wire 62 which is grounded at 63 on some part of the standard which is in electrical contact with the rod 13 upon which the detectors 9 are pivotally mounted. The spring contact fingers 58, 59

are normallyspaced apart and held in closed position by a pin 64 of insulated material, which pin is fixed in a projection 65 offset from the wei hted arm 49.

From the oregoing, it will be seen that when one or more of the detectors fall upon or come into contact withthe bar 15, the electrical circuit will be closed and the battery 61 will energize the electromagnet56, which in turn will attract the armature 55, lift the notch 53 from the lug 54 on the weight 50 and allow the; arm 49 of the member 45 to rock by gravity on its pivot 46 so the contact that the toe 47 will. engage the finger 48 and actuate the latch 40. When the latch 40 is released from the lug 42, the spring 39 on the rod 35 will exert its pressure on the 1 brake lever 30, which will be raised so as to bring the friction pad 32 thereon into engagement with the pulley 17 and force it upwardly against the friction pad 33 on the study 34.

As the weighted arm 49 is rocked on its 16 pivot 46, the in 64 is also moved away from ngers 58,. 59, which normally sprin apart and break the electrical circuit,- there y deenergizing the 'electromagnet 56 which immediately releases the armature 55 and the bell crank 51 falls to the position shown in Fig.1.

- In order to reset the brake lever 30 and actuatev the member 45 simultaneously, we provide a rocking element 66 pivoted at 67, which element has oppositely disposed arms 68, 6,9, of which'the arm 68 is arranged to be engaged b an abutment 70 having av screw threade adjustment on a rod 71,-the upper end of I Wl'llCl'l rod is pivotallyxcon fl nected at 72 to the brake lever 30 While the lower end of the rod may be connected to a foot treadle (not shown). A'rod 73 is pivotally connected to the weighted arm 49 at 74 and is provided with an abutment 75 which is screw threaded on the rod 73 andmay be adjusted in position thereon to be engaged by the arm 69' of the rocking ele ment 66.

Thus itwillbe seen that the brake lever 30 is pressed downwardly, against thetension of the spring 39 on the rod-35, the abutment 70 on the rod 71 will be brought into engagement with the arm 68, which will rock the element'66 and raise the arm 69 into contact with the abutment 7 5, which in turn will move the weighted arm 49 upwardly until the lug 54 is brought into en-v gagement with the notch 53 of the bell crank 51. This upward movement of the weighted no arm 49 lifts the toe 47 awayfrom the finger 48 of the latch 40 and allows the latch to be moved by its spring 43 so as to engage the lug 42 on the brake lever 30. Y

' For registering the length of' yarn to be reeled, we provide a spur gear 76 mounted on a stud shaft 77, carried by the arm 18*, which spur gear 76 meshes with the spur gear 21 on the stud shaft 18. .A worm 78 is fixed to rotate with the spur gear 76and arranged to engage the teeth of the. worm wheel 79 fast on one end of a shaft 80 mounted in bearings 81, 82 carried by the standard 1. The otherendof the shaft 80 has a worm 83 which meshes with a worm 325 wheel 84, the side of which is divided into sections indicating, in the present instance, yards. The numerals illustrated on the side I of the worm wheel, 84, are placed at one fifth of a circumference apart, the interval :3

between two numbers being the distance which the registering wheel will move for winding two hundred yards.

The worm wheel 84 is provided with an elongated hub 85, (see Fig. 3) the outer end of which has a screw threaded engagement with a stud 86, secured to one arm 87 of a bell crank lever 88, which is pivoted at 89 on the standard 1, so that as the worm wheel 84 is rotated it will be moved laterally on the stud 86. The worm wheel 84 may be manually moved toward and away from the worm 83 by means of the other arm 90 of the bell crank lever 88,- which arm 90 has a pin 91 yieldingly mounted therein and arranged to seat in a recess 92 in a bracket 93 fixed-to the standard 1. When the pin 91 is released mined by a stop 94 on the worm wheel 84 coming in contact with a stop finger 95 adjustably mounted on the standard 1. a In order to provide for the stoppage of the ma-- chine after a predetermined quantity or length of thread has been reeled,-we provide an index finger 96 having a split collar 97, adjustably secured on the hub 85 anda tail 98. The index finger 96 indicates the number of yards to be reeled, while the tail 98 which is diametrically opposite the finger is constructed to engage a spring actuated bell crank latch 99, pivoted at 100 on an ear 101 extending outwardly from the hub of the friction pad 33. One arm 102 of this latch 99 has a lug 103 arranged-to be engaged by an abutment 104 on the tail 98,.while the other arm 105' is provided with a notch 106 which coacts with a hook 107 offset from a finger 108 of an oscillating signal 109. This signal 109 is mounted. to rock on a pivot 110 carried by the ear 101 and held in the position shown in Fig. 2 by the coaction of the notch 106 and. hook 107. When the signal 109.is tripped by the abutment 104 striking the lug 103, it will rock the latch 99 so that the notch 106 will be free of the hook 107 and the signal 109 will fall by gravity to the position shown in Fig. 1 and in dotted outline in Fig. 4. In this pisition the finger 108 will contact with a pm 111 which is insulated from the standard 1 and is connected by a wire 112 to the wire 57 of the electrical circuit previously described.

It will therefore be seen that since the signal 109 is grounded on the standard 1,'the finger 108 contacting with the stop pin 111 will form the connection to complete the circuit and the battery 61 will energize the electromagnet 56 which will attract the armature 55, lift the notch 53 from the lug 54 of the weight 50 and allow the arm 49 to rock on its pivot 46 so that the toe 47 will engage the finger 48 and actuate the latch 40. When the latch 40 is released from the la 42 on the brake lever 30 the sprin 39 wi l cxert its pressure on the brake lever 30, which will be lifted, causing the pad 32 to enga frictibn pad 33 on the stud 34, thereby disengaging the pulley 17 from its contact with the drive pulley of the reel 12.

In order that the signal may be visible, at

the proper moment, we provide a guard or shield 113, shown in dotted outline in Fi s. 1, 2 and 3, which guard is spaced a slig t distance from the worm wheel 84 so that the signal may move therebetween and be ob.- scured from view, when in the position shown in Figs. 2 and 3. This guard may supported from the standard 1 in any well known or approved manner and extended around the worm wheel 84 to serve as a protection therefor.

It will also be understood that as the weighted arm 49 is moved downwardly, the insulated pin 64 will be moved away from the contact finger 59 so that the fingers 58, 59 will spring apart and break the electrical circuit, thereby de-energizing the electromagnet 56, which releases the armature 55, so that the bell crank 51 will fall by gravity to the position shown in Fig. 1.

While we have shown and described our invention as applied to a reeling machine, we wish it clearly understood that our improved mechanism may be readily applied to a winding or similar machine using cops or spools.

\ We have also shown and described certain features which are not claimed herein, but are the subject matter of a copending ap- 20 and stopping the rotation "e the pulley 17 and force it against the plication, Serial No. 51.604, filed August 21,
